Testing New Pulse Stretcher
Sometimes working with laser pulses that are just femtoseconds in duration can make the job much harder! With very short laser pulses, all of the energy in the pulse is squeezed into a very short burst, this means that the peak power in the laser pulse can be very high...

3D Printed Vacuum Chamber
Experiments during the first year of the LEAF-2D project showed that Laser Induced Backwards Transfer (LIBT) of 2D materials can be very difficult in an atmosphere of air. The 2D materials tend to break-up into fragments as they fly through the air before landing on the intended receiver surface...

Bi Se S growth on Sapphire (BAR ILAN UNIVERSITY)
2 (3-x) x
A material growth achieved by a chemical vapor deposition method of thin layer manufacturing.
The material Bi2Se(3-x)Sx created as big flat hexagonal shape. The substrate material is sapphire.
MoS growth (BAR ILAN UNIVERSITY)
2
A material growth achieved by a chemical vapor deposition method of thin layer manufacturing. The material MoS2 created as a flat mono-layer triangle shape. The substrate material is silicon wafer. A Raman shift and photoluminescence characterization graphs are presented
